我們工廠的紅外人體感應(yīng)探頭的腳數(shù)不同，功能也有所區(qū)別：### 三腳探頭- **VCC**：電源正極- **GND**：電源負(fù)極- **OUT**：信號輸出### 四腳探頭- **VCC**：電源正極- **GND**：電源負(fù)極- **OUT**：信號輸出- **EN**：使能控制（可選）### 六腳探頭- **VCC*……

Q: No high level appeared when pir was testing the timing. Did pir crash? Answer: pir is not dead, it should be PIR data ready to produce high power, is forced to pull down by the MCU. You can directly supply power to the pir, use the oscilloscope to see

1. The connection between the PIR and other devices should be as short as possible. On the dual panel or multi-layer board, try not to route the cable below the……

MSL： 通常封裝完的IC，膠體或Substrate PCB 在一般的環(huán)境下 會吸收濕氣，造成IC在過 SMT回流焊時，發(fā)生“爆米花”(POPCORN)的狀況。濕氣敏感性等級(Moisture Sensitivity Level，MSL) 被用來定義 IC 在吸濕及保存期限的等級，若IC超過保存期限，則無法保證不會因吸收太多濕氣而在SMT回 流焊時發(fā)生 POPCORN現(xiàn)象。因此對于超過保存期限的 IC 要進(jìn)行烘烤。

Xinyongcheng photoelectric infrared tube DEMO board is a kind of experimental board used to demonstrate the working principle and performance of infrared tube. It uses high quality infrared tube sensor and precision electronic components, with high accura

PIR sensor Features: Low power consumption, stable technical performance, low price, etc. PIR sensor application: It is widely used in the field of electronic anti-theft, human body, animal detector. Passive Infrared (PIR) sensor definition: A

A PIR lens, also known as a Fresnel lens, is a thin sheet made from a polyolefin material. One side of its surface is smooth, and the other side is burned with concentric circles from small to large. This texture is designed by using the dry interference

Customer C: The photosensitive surface of the sample XYC-PT5E550BC-I8 anti-infrared photosensitive device you provided is on the top, right? Xin Yongcheng: Yes, C worker Customer C: But the operating voltage is 5V. I want a 3.3V

PIR (Passive infrared) sensors usually require infrared lenses to work properly. A PIR sensor is a type of sensor used to detect a human body or other heat source, which works by measuring the temperature difference between the target object and it

在智能家居領(lǐng)域，雷達(dá)感應(yīng)和人體感應(yīng)是兩種常見的技術(shù)，它們都可以用于實(shí)現(xiàn)自動化控制和智能監(jiān)測。然而，對于哪種技術(shù)更好，卻因人而異。下面我們將從幾個方面對雷達(dá)感應(yīng)和人體感應(yīng)進(jìn)行比較，以便幫助您做出更好的選擇。 感應(yīng)范圍 雷達(dá)感應(yīng)的感應(yīng)范圍相對較廣，可以覆蓋到數(shù)米至數(shù)十米的距離。而人體感應(yīng)的感應(yīng)范……

問：紅外器件焊接測試，烙鐵超過2秒，塑料支架就燙化了？器件是能過smt的吧？答：1，器件是能過smt的， 2，烙鐵焊的時候注意，不要燙到塑料，可以焊接在焊盤的那個引腳上面。 3，或者用加熱臺加熱焊接。 回流焊接 Reflow Soldering ● 回流焊次數(shù)不可以超過一次，否則 ALS 可能……
